Picture a pharmacist reviewing their credit ledger. Say they have 34 credit accounts open, and the oldest outstanding balance is 14 months old — ₹67,000 uncollected in total. Ask how often they follow up, and a common answer is some version of "I remind them when they come in." A few of those accounts may not have come in since the credit was extended.
That ₹67,000 did not disappear in one bad decision. It left in ₹400 and ₹800 increments, one prescription at a time, to people the pharmacist trusted. The register showed the sale. The shelf lost the stock. The bank account never saw the cash.
If you are reading this because you are weighing whether to extend credit — or because you already have and you are not sure how to think about what you are owed — this post is the clearest framework we can give you. Ignore it, and customer credit may quietly cost you more than a full-time employee's annual salary without you ever noticing a single large loss.

The Silent Cash Flow Problem Nobody Budgets For
Consider a neighborhood pharmacy that extends credit only to "regulars." Ask them to define a regular, and the answer is often: someone who has come at least twice. That is a thin criterion for handing over medicines worth ₹600 to ₹2,500 per visit.
The structural problem is that pharmacy credit is informal credit. There is no signed agreement, no repayment schedule, and no collateral. The customer has already received the product. The pharmacist's only leverage is the relationship — and using that leverage feels uncomfortable every time.
The annual cost compounds faster than most owners realize. If a pharmacy turns over ₹50 lakh a year and 4% of that revenue sits in uncollected credit at any point, that is ₹2 lakh in working capital tied up in receivables — capital that cannot buy new stock, cannot service supplier debt, and earns zero return.
Regulatory Risk You May Not Have Considered
Credit itself is not illegal, but the record-keeping around credit sales carries compliance weight that most pharmacists underestimate.
Every Schedule H and H1 medicine dispensed — governed under Rule 65 of the Drugs and Cosmetics Rules — must be recorded and available for inspection, and Schedule H1 sales also go into a separate register (the prescriber's name and address, the patient's name, the drug and its quantity) kept for three years under Rule 65(3)(h). A credit sale is still a sale. If the credit customer's name, prescription details, and dispensing record are maintained only in your memory or on a loose paper chit, you are exposed. Selling a Schedule H1 drug without a prescription is punishable under Section 27(d) of the Drugs and Cosmetics Act, 1940: imprisonment of one to two years and a fine of not less than ₹20,000.
There is a second layer. Under the Digital Personal Data Protection Act 2023, if you are collecting customer names, phone numbers, and health-related purchase histories as part of running a credit ledger — even informally in a notebook — you are processing personal data. The Act's obligations are being phased in, but the direction is clear: informal data collection with no retention or deletion policy will become a liability.
Credit creates records. Make sure your records are defensible.
What Happens When a Good Customer Becomes a Collection Problem
The pharmacist usually knows the moment a credit account crosses from "slow to pay" to "probably lost." It is when the customer starts sending someone else to collect medicines, or stops coming entirely, or answers the phone differently.
At that point, the pharmacist faces an uncomfortable set of options:
- Write it off silently and absorb the loss
- Chase the customer and risk damaging a relationship that has years of legitimate business behind it
- Escalate to a formal dispute — which, for ₹3,000, makes no practical sense
None of these options are good. The only real answer is to prevent the account from reaching this stage, which means deciding upfront which customers get credit, what limits apply, and what the follow-up cadence looks like before the first rupee leaves the shelf on credit terms.
Left alone, an uncollected credit account can sit unpaid for months before the owner acts, and the older a balance gets, the harder it is to collect. The practical reality is that a balance older than 90 days in an informal credit arrangement is often closer to a gift than a receivable.
What a Pharmacy With Disciplined Credit Looks Like
The difference between a pharmacy hemorrhaging money through credit and one that uses it profitably is almost never the decision to offer credit. It is the system around it.
Here is what the before and after looks like in practice:
| Without a system | With a system |
|---|
| Credit given based on gut feel | Credit only above a defined repeat-purchase threshold |
| Balance tracked in a notebook or remembered | Balance visible per customer at point of sale |
| Follow-up happens when the pharmacist remembers | Automated follow-up trigger at 7, 14, and 30 days |
| Write-off discovered at year-end | Aging report reviewed weekly |
| No visibility into which customers are chronic late payers | Payment history visible before next credit is extended |
The pharmacist who does this well is not harder on customers. They are clearer with them. When a customer knows at the counter that their outstanding balance is ₹1,200 before a new purchase is put on credit, the conversation is straightforward. When the pharmacist does not know — or does not say — the balance grows and the awkwardness of the eventual conversation grows with it.
How Nesayo Handles Credit Without Losing the Relationship
On Nesayo's billing — free forever — a bill can be saved as Credit (udhaar) in one tap, against the customer's name. Unpaid bills stay marked pending in the bill history until you tap Mark Paid, and asking the chat "who owes me money" or "pending dues" brings up what is outstanding. You do not have to run a report to find out.
Make "who owes me money" part of the morning check, so a balance is seen the day it appears. (Payment Advisor, on the Full plan at ₹549/month as of October 2026 — see current pricing at nesayo.com/pricing — watches the other side of the ledger: what you owe your distributors.)
Picture the change this way: without a daily check, a pharmacy might discover at month-end that three accounts had crossed ₹5,000 combined. With one, the pharmacist can call the day a balance shows up, while it is still small enough for the conversation to feel routine rather than confrontational.
A credit sale of a Schedule H1 medicine is logged at billing like any other H1 sale: date, medicine, batch, quantity and bill number, with the patient and prescriber names entered on the bill. Nesayo does not record the prescriber's address yet, so the pharmacist adds it to complete the Rule 65(3)(h) register.
A catalogue of more than 2.5 lakh medicines — and, on the paid plans, voice billing (beta) in Hindi and English — mean the pharmacist does not slow down the counter to log a credit transaction manually. The record exists because the sale was billed, not because someone remembered to write it down later.

The Choice in Front of You
Every month you run informal credit without a tracking system is a month where the real cost of that credit is invisible to you. You will know what you sold. You will not know what you collected. The gap between those two numbers is the number that matters — and right now, for most pharmacies running paper or notebook-based credit ledgers, that number is a guess.
That hypothetical pharmacist, asked to estimate their exposure from memory, might guess "around ₹20,000" — off by more than three times from the ₹67,000 actually outstanding. The gap isn't a bad memory. It's the absence of a system.
Go to nesayo.com/demo — a sample pharmacy is pre-loaded, no signup required. Save a bill as Credit (udhaar), then ask the chat "who owes me money" and see what it lists. It takes under two minutes to see whether the system fits how your counter actually runs. If it does not, you have lost two minutes. If it does, you will know what your uncollected payments look like as soon as your bills are in.

FAQ
How do I keep track of customer credit in a pharmacy without billing software?
Most pharmacies use a paper khata or a notebook with one page per customer. The main risk is that balances are only as accurate as the last time someone updated the entry, and aging — how long a balance has been outstanding — is almost impossible to see at a glance. A simple spreadsheet with columns for customer name, date of credit, amount, and date of payment is a meaningful step up from a notebook.
Is there a legal limit on how much credit a pharmacy can extend to a customer in India?
There is no specific statutory cap under the Drugs and Cosmetics Act or GST law on the rupee amount of credit a pharmacy may extend. Credit terms are a business decision. However, any credit sale of Schedule H or H1 medicines still requires a valid prescription, and the sale must be recorded — a Schedule H1 sale in the separate H1 register under Rule 65(3)(h) — regardless of whether payment is received at the time of dispensing.
Can I charge interest on overdue pharmacy credit balances?
You may, but only if it is agreed in writing with the customer before credit is extended. Charging interest on informal credit with no prior agreement is legally difficult to enforce and tends to damage the customer relationship. In practice, many retail pharmacies choose not to charge interest on credit balances.
What happens to GST liability on a credit sale where the customer never pays?
GST liability under the HSN 3004 category for medicines arises at the point of supply — which is the date of invoice, not the date of payment. If the customer never pays, you have already paid GST on that sale, and GST law has no general bad-debt relief for the seller, so that tax usually stays paid. Verify the treatment of your specific invoices with your CA.
How do I politely refuse credit to a customer without losing them?
The least damaging approach is a policy rather than a personal decision. If your counter follows a rule — "we do not extend credit above ₹500 without a prior balance being cleared" — the pharmacist is not the one saying no, the policy is. Most customers accept a clear policy better than they accept what feels like a personal judgment about their trustworthiness.
At what point should I write off pharmacy credit as a bad debt?
There is no single rule, but industry practice for informal receivables is to flag any balance over 90 days as high-risk and any balance over 180 days as likely irrecoverable for practical purposes. For the accounting treatment of bad debt, your CA will need to review the specific invoice details. Writing it off in your own ledger is a business decision; the GST already paid on the sale generally cannot be claimed back, so ask your CA before assuming otherwise.
How does Nesayo's Payment Advisor help with overdue customer credit?
Payment Advisor is one of five AI agents on Nesayo's Full plan (₹549/month as of October 2026; verify current pricing at nesayo.com/pricing), and it watches the other side of the ledger: what you owe your distributors — payments due in the next three days, overdue ones, and early-payment discounts. For customer credit, on every plan unpaid Credit bills stay marked pending in bill history, and the chat answers "who owes me money" with your outstanding dues. The goal is to have the conversation while the balance is still small enough to be easy, rather than after it has grown into a write-off.
Does giving customer credit affect my GST filing in any way?
The sale is recorded at the time of invoice, so it appears in your GSTR-1 in the period it was billed regardless of when — or whether — the customer pays. Credit terms do not change the reporting period. Where GST intersects with credit is when the receivable becomes a bad debt: GST law has no general bad-debt relief for the seller, so the output tax already paid usually stays paid. That analysis should be done with your CA rather than based on a general rule.
